'MACHINE FOR MAKING CAPS AND FOR APPLYING THE SAME T0 BOTTLES.

To all 107mm t may concern.' v

Be it known that I, ANDERS ANDERssoN RosiiNonnN, a subject of the King of Sweden, and resident of 70b Sdra Frstadsgatan, Malmo, in the Kingdom ofV Sweden, have invented certain new and useful Machines for Making Caps and for Applying the Same-to Bottles, of which the following is a specification, reference being made to the accompanying drawings.

rlhe present invention relates to improvements in machines for capsuling or sealing bottles or other vessels.

In earlier machines for the manufacture of capsules and for the capsuliiig or sealing of bottles or other vessels by means of capsules provided with a sealing disk, in which machines the blanks, of which the capsules are formed, are cut yout or punched out by one tool and the sealing disks by another tool, the tools are arranged co-axially, the one tool inclosing the other. This arrangement has been found to entail great inconveniences, especiallyT when shavings of the metal strip and fragments of the strip of cork or the like, from which strips the capsules and the sealing disks respectively are obtained, collect in the female dies in which the capsule blanks areV formed into capsules, and have injurious effects both on the forming of the capsules and on the working of the machine. The earlier machines of the above type cannot manufactureany but cylindrical capsules, and they are incapable of making the so-called crown corkswhich are in extensive use.

The above-mentioned and other inconveniences are obviated and considerable advantages are attained by arranging machines intended for the purposes in question in occordance with the present invention e. so that the said tools are situated or act successively to one another,v that is to say so that a capsule is first formedy in a female die and then, after the female die has been moved, a sealing disk, which may be integral or composite, is placed in the capsule obtained. y i* 'Y The annexed drawings show by way of example a form of the present invention adapted to a machine for the manufacture of crown corks and for the capping'or seal ing of bottles with them. Figure ll shows a vertical section and Fig. 2 a horizontal section of the machine` head, `which contains the parts operating in the manufacture of Y Specication of Letters Patent. .Application filed .Tune 30, 15520.

thecapsules and the sealing of the bottles, while Fig 3 shows a detail in section. Fig. a is a diametrical section of one of the caps.

. 'As in earlier machines for the said purpose (for example the applicants Swedish f Patent No. 40480) there is rotatably located 1n the machine head a cylinder l, wherein there are female dies, in which the capsules are formed, and which cylinder rotates intermittentlyin the manner described below. rfhe power required for this movement and for the movement of other parts situated in the machine head is supplied from an intermittently rotated vertical shaft 2 driven from the main shaft of the machine, and the device for bringing about the intermittent niovement of the female die cylinder may be constructed inany suitable manner whatever.

T he snaft 2 is provided with a fixed miter gear 2a, which drivesa similar gear 2 on the shaft 22. The gear 2" is provided with a hub 2c to which is fixed a lgear 2, which drivesa gear 2e xed tothe cylinder l. In this manner the cylinder 'l is driven from the shaft 2.

The female die cylinder l is provided with tivo diametrically .situated female dies. Each of said female dies is formed of a bottom piece 3, which is firmly fastened to the cylinder by a bolt 4. and of a sleeve 5 surrounding the bottom piece and slidable around it. The displacement of thesleeves 5v is effected in the manner and for the purpose stated more clearly hereinafter.

VAbove the female die, beinfr in position for the forming of a capsule, is situated the tool for the production of the capsule blanks.y Said tool consists of a tubular punch 0, which'is movable in a vertical direction, and which, with the aid of a punch die 0a, punches the capsule blanks outof a strip (not shown) consisting, foir instance, of aluminum, iron or an alloy, said strip being intermittently fed forward under the tubular punch G e. through the channel 7) by a pair of cani rollers 8. rlhese rollers are provided with meshing gears 821-8", the latter of which is fixed to a shaft 8C. Agear 8d is fixed to the shaft and meshes with a gear. Se fixed to the shaft 22. lt will thus be Seen Vthat the rollers 8 are driven from the shaft 22.

ln the tubularl punch 6 there is a piston 9,

likewise movable in a vertical direction and at the lower end of which there is a male die 10, the shape of which corresponds to the desired shape of the capsules.

The device by which the required movement is imparted to the tubular punch 6 and the piston 9 or the male die 10 respectively may be of any kind desired. Power for this operation is obtained from the main shaft by means of a reciprocating link 11a, which rocks a lever 11 that is connected to the piston 9.

Fingers 9a are pivotally mounted in the head of the machine and engage notches 9b in the sides of the piston 9. lhen the piston 9 is depressed, the fingers are swung downwardly until they engage the upper end of the punch 6, and further downward movement of the piston 9 causes the fingers to depress said punch.

After a capsule blank has been punched out of the blank strip by the tubular punch 6 during the downward movement of the latter, it is carried by the tubular punch down toward the upper edge of the female die and lodges centrally on the female die between which and the tubular punch it is held firmly until the male die 10, by a drawing operation on the blank, descends into the female die and forms a capsule. In the present case the capsule is assumed to be a capsule for a so-called crown-cork.

After the above described process and when the tubular punch 6 and the male die 10 have been carried by a spring 6" back to their original positions, the female die cylinder 1 revolves a quarter turn counterclockwise (Fig. 1), so that the female die with the newly formed capsule situated therein will be opposite to the tool for the forming of the sealing disks. This tool is shown to consist of a punch piston 12, which coperates with a punch die 12a and which receives its functional movement from a cam disk 13 driven through the gearing 13a, 13b, 13, 13d and 13e from the shaft 2, its return movement being effected by a spiral spring 111. The strip, consisting` of cork or other suitable material (and which also may be composed of several different strips and materials), from which the sealing disks are punched out, moves beneath a plate 15 to cam rollers 16, by which the ribbon is intermittently fed down to a position in front of the punch piston 12. After a sealing disk has been punched out, it is driven by the punch piston kthrough the punch die and into the newly formed capsule situated opposite those parts, against the bottom of which the sealing disk is pressed, as will be seen from Fig. t, which shows a section of a` crown cork with sealing disk. The rollers 16 are provided with meshing gears 16a, one of which is fixed to a shaft 16, having a fixed gear 16c driven from a gear 16d fixed to the hub of the gear 13d.

When the newly formed capsule has been provided with a sealing disk, the female die cylinder revolves another quarter turn in the previously indicated direction, in consequence of which the female die hitherto referred to will be in a position for sealing a bottle 17 by means of the capsule situated in said die. rlhe other female die in the female die cylinder will simultaneously be in a position for forming another capsule.

Against the bottoms of the sleeves 5, which together with the bottoni pieces 3 form the female dies, rest levers 18, each of which at one end is pivotally fixed in the female die cylinder and the other end of which is acted upon by a member 19 form ing one arm of a double-armed lever, the other arm 2O of which is acted upon by a cam 21 on a shaft 22 driven from the shaft 2.

When a female die containing a capsule provided with a sealing disk has reached the position just stated, c'. e. the sealing position, the cam 21 acts on the lever 20, the arm 19 of which in turn acts on the lower one of the levers 18, in consequence of which the corresponding female die sleeve 5 is pressed downward. A moment previously,

the bottle 17 which is to be sealed has been moved upward, so that the mouth of the bottle is held strongly jammed against the sealing disk in the capsule, while the female die sleeve is moving downward. During its downward movement the sleeve acts on the edge portion 23 (see Fig. l) of the capsule, whereby the knee-shaped portions 24, which are situated between the edge portion 23 and the cylindrical or somewhat conical capsule portion 25, which surrounds the sealing disk, are caused to engage with a groove which in the usual manner is arranged on the bottle neck under the bottle mouth. rlhe sealing of the bottle is now completed. During the process just described a fresh capsule has been formed in the upwardly facing female die. When the sealed bottle has been lowered somewhat, the female die cylinder turns again, so that the new capsule will come into position to be provided with a sealing disk, and then the cylinder is turned again for the purpose of bringing the capsule provided with a sealing disk into the position to be applied on a following bottle. This cycle may be continued as long as desired.

The return movement of the female die sleeves 5 is effected by spiral springs 5a.

On the outer end of the channel 7 there is a shear device 26 driven from the lever 11 for cutting the part of the capsule blank strip, from which the blanks have been punched out, intoshort pieces, which fall down into' a suitable receptacle.

Sealing machines arranged in accordance with this invention may I be constructed otherwise than has been stated by way of example. Thus, for example, the female die cylinder (or corresponding part), instead of being provided with a pair of female dies, may be provided with two or more pairs. ln this case, obviously, each rotary movementV of the female die cylinder will be of less extent than when only one pair of fefor providing the latter with sealing disks and for applying them on the bottles should be arranged in conformity therewith,

lt is obvious that other capsules than socalled crown corks can be made with machines constructed in accordance with this invention. Thus, for example, capsules with a smoothor folded circumference can be made with them. Y

With regard to the arrangement ofthe details shown, it should be observed that the springs, which effect the return movement of the respective members, may suitably be replaced by devices which ultimately will be found more reliable than springs; springs have been shown in the drawings only for convenience of illustration.
